安装前可以查看交给 AI 代理的指令内容。
Modern utility-first CSS with CSS-native configuration.
| v3 (Legacy) | v4 (Current) |
|---|---|
tailwind.config.js | CSS-based @theme directive |
| PostCSS plugin | Oxide engine (10x faster) |
| JIT mode | Native, always-on |
| Plugin system | CSS-native features |
@apply directive | Still works, discouraged |
| Concept | Description |
|---|---|
| CSS-first | Configuration in CSS, not JavaScript |
| Oxide Engine | Rust-based compiler, much faster |
| Native Nesting | CSS nesting without PostCSS |
| CSS Variables | All tokens exposed as --* vars |
@theme {
/* Colors - use semantic names */
--color-primary: oklch(0.7 0.15 250);
--color-surface: oklch(0.98 0 0);
--color-surface-dark: oklch(0.15 0 0);
/* Spacing scale */
--spacing-xs: 0.25rem;
--spacing-sm: 0.5rem;
--spacing-md: 1rem;
--spacing-lg: 2rem;
/* Typography */
--font-sans: 'Inter', system-ui, sans-serif;
--font-mono: 'JetBrains Mono', monospace;
}
| Action | Use When |
|---|---|
| Extend | Adding new values alongside defaults |
| Override | Replacing default scale entirely |
| Semantic tokens | Project-specific naming (primary, surface) |
| Type | Responds To |
|---|---|
Breakpoint (md:) | Viewport width |
Container (@container) | Parent element width |
| Pattern | Classes |
|---|---|
| Define container | @container on parent |
| Container breakpoint | @sm:, @md:, @lg: on children |
| Named containers | @container/card for specificity |
| Scenario | Use |
|---|---|
| Page-level layouts | Viewport breakpoints |
| Component-level responsive | Container queries |
| Reusable components | Container queries (context-independent) |
| Prefix | Min Width | Target |
|---|---|---|
| (none) | 0px | Mobile-first base |
sm: | 640px | Large phone / small tablet |
md: | 768px | Tablet |
lg: | 1024px | Laptop |
xl: | 1280px | Desktop |
2xl: | 1536px | Large desktop |
w-full md:w-1/2 lg:w-1/3| Method | Behavior | Use When |
|---|---|---|
class | .dark class toggles | Manual theme switcher |
media | Follows system preference | No user control |
selector | Custom selector (v4) | Complex theming |
| Element | Light | Dark |
|---|---|---|
| Background | bg-white | dark:bg-zinc-900 |
| Text | text-zinc-900 | dark:text-zinc-100 |
| Borders | border-zinc-200 | dark:border-zinc-700 |
| Pattern | Classes |
|---|---|
| Center (both axes) | flex items-center justify-center |
| Vertical stack | flex flex-col gap-4 |
| Horizontal row | flex gap-4 |
| Space between | flex justify-between items-center |
| Wrap grid | flex flex-wrap gap-4 |
| Pattern | Classes |
|---|---|
| Auto-fit responsive | grid grid-cols-[repeat(auto-fit,minmax(250px,1fr))] |
| Asymmetric (Bento) | grid grid-cols-3 grid-rows-2 with spans |
| Sidebar layout | grid grid-cols-[auto_1fr] |
Note: Prefer asymmetric/Bento layouts over symmetric 3-column grids.
| Format | Advantage |
|---|---|
| OKLCH | Perceptually uniform, better for design |
| HSL | Intuitive hue/saturation |
| RGB | Legacy compatibility |
| Layer | Example | Purpose |
|---|---|---|
| Primitive | --blue-500 | Raw color values |
| Semantic | --color-primary | Purpose-based naming |
| Component | --button-bg | Component-specific |
| Type | Recommended |
|---|---|
| Sans | 'Inter', 'SF Pro', system-ui, sans-serif |
| Mono | 'JetBrains Mono', 'Fira Code', monospace |
| Display | 'Outfit', 'Poppins', sans-serif |
| Class | Size | Use |
|---|---|---|
text-xs | 0.75rem | Labels, captions |
text-sm | 0.875rem | Secondary text |
text-base | 1rem | Body text |
text-lg | 1.125rem | Lead text |
text-xl+ | 1.25rem+ | Headings |
| Class | Effect |
|---|---|
animate-spin | Continuous rotation |
animate-ping | Attention pulse |
animate-pulse | Subtle opacity pulse |
animate-bounce | Bouncing effect |
| Pattern | Classes |
|---|---|
| All properties | transition-all duration-200 |
| Specific | transition-colors duration-150 |
| With easing | ease-out or ease-in-out |
| Hover effect | hover:scale-105 transition-transform |
| Signal | Action |
|---|---|
| Same class combo 3+ times | Extract component |
| Complex state variants | Extract component |
| Design system element | Extract + document |
| Method | Use When |
|---|---|
| React/Vue component | Dynamic, JS needed |
| @apply in CSS | Static, no JS needed |
| Design tokens | Reusable values |
| Don't | Do |
|---|---|
| Arbitrary values everywhere | Use design system scale |
!important | Fix specificity properly |
Inline style= | Use utilities |
| Duplicate long class lists | Extract component |
| Mix v3 config with v4 | Migrate fully to CSS-first |
Use @apply heavily | Prefer components |
| Principle | Implementation |
|---|---|
| Purge unused | Automatic in v4 |
| Avoid dynamism | No template string classes |
| Use Oxide | Default in v4, 10x faster |
| Cache builds | CI/CD caching |
Remember: Tailwind v4 is CSS-first. Embrace CSS variables, container queries, and native features. The config file is now optional.
